摘要
PDC钻头是随着PDC复合材料的发展而发展起来的一类新型钻井工具。在钻井施工过程中,为了提高钻进效率,降低成本,对PDC钻头进行选型研究是必要的。通过层次分析方法,建立PDC钻头分析目标层,影响因素准则层以及钻头型号方案层的关系,构造判断矩阵,建立优选模型。结合大庆中深井的钻井实际情况,基于中深井钻头数据库,进行钻头优选,得出大庆油田某地区中深井PDC钻头选型方案,并在实践中得以验证。
PDC bit is a new drilling tool which develops along with PDC composite material. In order to increase drilling efficiency and reduce cost during drilling operations, it is necessary to do some research on PDC bit selection. According to Analytical Hierarchy Process, the relationships among analyzing target level, principal level of influencing factor and alternative level is built, tion model is established. Based on bit database, the judgment matrices is constructed, and then the the model is applied in deep drilling practice in Daqing optimizaOilfield, and bit optimization design in District Anda is taken as an example to analyze the model, finally the optimum PDC bit selecting program is presented, and it is approved in practice
